Is it a CMP bean or a BMP bean? You do realize that accessing entities
directly from a JSP is probably not going to perform well on a variety
of application servers, right?
Also, Tomcat is known to not be the fastest JSP engine out there.

Are those times averaged, or first-run. You'll find that JBoss under
hotspot gets quite a bit faster in subsequent runs.

I've been looking at performance a bit. This was on haitus while we get
the ECPerf stuff running so that we have real-world(ish) test cases.
